What is the reason for bloody discharge from leucorrhea after intercourse?

Bloodshot leucorrhea after intercourse may be caused by vaginal mucosal damage, cervicitis, cervical polyps, endometriosis, cervical cancer and other factors. It is recommended to seek medical treatment promptly for a clear diagnosis to avoid delays in treatment.

1. Vaginal mucosal damage

Excessive friction during sexual intercourse may cause slight tears in the vaginal mucosa, which may appear as a small amount of bright red blood mixed with leucorrhea. This condition is usually accompanied by a brief stinging sensation and the bleeding is small and stops on its own. It is recommended to suspend sexual intercourse, keep the perineum clean and dry, and avoid using irritating lotions. If bleeding lasts for more than two days or is accompanied by significant pain, other pathological factors need to be ruled out.

2. Cervicitis

Patients with chronic cervicitis are prone to contact bleeding after intercourse. The leucorrhea is often yellow-green with blood streaks, and may be accompanied by a feeling of distension in the lower abdomen. Pathogen infections such as gonococcus and chlamydia are common causes. The diagnosis requires gynecological examination and secretion testing. For treatment, Baofukang suppositories, anti-metritis tablets and other drugs can be used. In severe cases, physical therapy is required.

3. Cervical polyps

Polyps formed by hyperplasia of cervical mucosa are fragile in texture, and mechanical stimulation during intercourse may cause capillaries on the surface of the polyps to rupture. The typical manifestation is painless bleeding, and the blood is mostly dark red and mixed with leucorrhea. For those with polyps exceeding 1 cm in diameter or recurrent bleeding, it is recommended to undergo hysteroscopic polyp removal, and postoperative pathological examination will rule out the possibility of malignant transformation.

4. Endometriosis

Endometrial tissue that is ectopic to the cervix will bleed under the pressure of sexual intercourse. The blood is often chocolate-colored and accompanied by progressive dysmenorrhea. Ultrasound examination shows abnormal echogenic masses in the cervix, and the diagnosis requires pathological biopsy. For treatment, dienogest tablets, gestrinone capsules and other drugs can be used to inhibit the growth of the endometrium, and if necessary, lesion resection can be performed.

5. Cervical cancer

Cervical cancer in the early stage may only show a small amount of bleeding after intercourse, and the blood is mostly light red or brown. In the late stage, there may be foul-smelling discharge. Persistent human papillomavirus infection is a major risk factor, and TCT and HPV screening can assist in diagnosis. Cervical conization, radical hysterectomy, etc. are selected according to the stage, and postoperative radiotherapy and chemotherapy are required.

You should pay attention to sexual hygiene every day, avoid multiple sexual partners, and be gentle during intercourse. Carry out regular gynecological examinations and cervical cancer screenings every year. Women over 40 years old are recommended to increase the frequency of screenings. After abnormal bleeding occurs, the bleeding time, color and accompanying symptoms should be recorded, and previous examination reports should be brought with you when seeing a doctor. During the treatment period, follow the doctor's advice to avoid sexual intercourse, wear cotton breathable underwear, and eat more broccoli, kiwi fruit and other foods rich in vitamin C to enhance immunity.
